New multifunctional LED high current charge pump

AnalogicTech's new versatile LED flash high current charge pump, AnalogicTech, announces the AAT3174, a high current, high efficiency charge pump for multifunction LED applications. The new device greatly simplifies application design supporting flash and continuous mode by allowing designers to control LEDs with AnalogicTech's Simple Serial ControlTM (S2CwireTM) interface or RSET reset pin. This unique feature allows designers to achieve up to 800mA with an external resistor. The serial bus provides a powerful tool for driving LEDs, but it still requires designers to spend time learning how to program and develop solutions. Designers who want to quickly and easily develop solutions that support both flash and continuous mode operation can run the AAT3174 between two modes with a simple on/off trigger switch. The AAT3174 helps maximize power efficiency in a wide range of flare modes by using a combination of 1X, 1.5X and 2X three-mode charge pumps and internal detection circuitry. This allows the AAT3174 to provide higher efficiency than a simple double voltage (2X) charge pump. For portable applications with small footprints, the AAT3174 requires only four external capacitors (two 1F clamp capacitors and two small bypass capacitors on VIN and VOU) and a resistor that sets the maximum regulated output current. The device also provides a wide range of protection circuits, including thermal management systems that protect the AAT3174 in the event of a shorted output pin. In addition, it integrates a soft-start circuit that reduces the quiescent current to less than 1A by disconnecting the load from VIN, protecting the device from excessive inrush current during startup. With a specified operating temperature range of -40 degrees to +85 degrees, the AAT3174 is available in a lead-free 12-pin 3x3mm TDFN package. The unit price for 1000 pieces is $1.82.

Board To Board Connectors

Antenk manufactures a wide range of application specific board stacking connectors which were designed and built to specific customer requirements. Our experienced staff has developed custom products in a variety of contact styles, pitches and stacking heights. Our designs range from new concepts to duplicating existing market products identically or with improvements. Many desigsn are produced using automated manufacturing processes to increase reliability and provide significant cost savings

Board to Board Connector

Board-to-board (BTB) connectors as the name indicates is used for connecting circuits board together. This kind of connectors are suitable for stacking circuits boards one over another. Flat flexible cables can be avoided using these kinds of connectors; moreover it makes the entire unit more compact. The commonly used BTB connectors are SMT connectors and Berg Strip. We will discuss about them in detail in the following section.

SMT CONNECTOR
Surface Mount Technology (SMT) connector is a commonly found board-to-board connector in advanced circuit boards. As the name indicates this connector is available only in surface mount model. It is carefully mounted on to the solder pads on the surface of the PCB.
SMT connectors are ideal candidate for miniaturization due to their small area of occupancy and stacking height. They are suitable for double layered or multilayered PCBs. They are designed for high performance and reliability.
They commonly found in advanced circuit boards in networking equipment, telephones, mobile phones, computers and other consumer electronics.

Board-to-board (BTB) connectors are used to connect printed circuit boards (PCB), electronic components that contain a conductive pattern printed on the surface of the insulating base in an accurate and repeatable manner. Each terminal on a BTB connector is connected to a PCB. A BTB connector includes housing and a specific number of terminals. The terminal is made from a conductive material (mostly copper alloy), and plated to improve conductivity and antirust. Terminals transmit the current/signal between PCBs connected by BTB; the housing is made of insulating material (mostly plastic).

The basic types of Board to Board Connector
Broadly speaking, board to board connectors are manufactured in the following types:
Pin Header
Elevated Pin Header
Socket
Elevated Socket
Shrouded Header
Box Header

The way mount Board to Board Connectors on a PCB
board to board connectors are available in through hole (TH) and Surface Mount (SMT) variants.
Locating pegs (also referred to as locating posts, alignment pins or board locks) are used to assist alignment of connectors to the PCB. Locating pegs are particularly useful when using surface mount components.

board to board connectors are available in the following pitches: 04mm/0.5mm/0.8mm/1.0mm/1.27mm/2.54mm/3.96mm/4.0mm
For experienced hardware designers choosing board to board connectors is second nature, for the uninitiated it can be daunting. We offer design support and will help guide you through the options available. If you need help with your board to board connector design, contact antenk. Where required antenk also offer non standard pitches.
